Duplicate emails often appear when merging PST files due to overlapping data, multiple backups, or improper import processes. While Outlook provides manual options like the Import/Export feature and manual cleanup, these methods can be time-consuming and unreliable for large PST files. A more efficient solution is using a professional tool like Mailvita Merge PST for Mac Tool, which allows users to merge multiple PST files safely while automatically removing duplicate emails and maintaining data integrity.
